Aaron Hernandez has been handed a punishment of 30 days in isolation for his role in an recent altercation with a fellow inmate that left his victim in pretty bad shape, according to NECN.com.

Bristol County Sheriff Thomas Hodgson has confirmed that Hernandez was involved in a jailhouse altercation. The attack occurred Tuesday in a common area of the Bristol County House of Correction in Dartmouth, where only one inmate at a time is supposed to be out of his cell. According to Hodgson, the fight between Hernandez and the victim lasted last than a minute and unlike reports from TMZ, Hodgson told ABC News it was unclear which person was the aggressor and that neither men required medical attention. However, according to TMZ, the victim was actually in handcuffs, therefore defenseless, at the time of the attack, while Hernandez had free reigns to beat the guy up pretty bad.

Hodgson is launching an investigation into why the two men were in the hallway together at the same time. Hernandez, who is usually in solitary confinement, was allowed to go for an isolated walk before the incident. The victim had alleged been harassing Hernandez all day and Hernandez just snapped.

In his new more restrictive unit, Hernandez must spend 23 hours a day in his cell in isolation. He will have one hour of recreational time and eat meals in his cell. He can forget about walking in the halls without handcuffs as he now must wear waist chains and leg irons when out of his cell.

Hernandez may be facing additional charges for his role in the altercation in addition to his first-degree and weapons charges.
